The proposal is for five years plus options for 2017 and 2018, according to Heyman.

Niese, eligible for arbitration next season, is under control of the team through 2015. The Mets modeled their offer — though likely for less money — after Derek Holland’s five-year, $28 million deal with the Texas Rangers.

The 25-year-old Niese is 22-23 with a 4.39 ERA over four seasons with New York, the bulk of his starts coming in 2010 and 2011.
